Abstract: Multi-layer substrates comprising top and bottom surface layers comprised of synthetic nonwoven fibers, and a melted thermoplastic material layer between the top and bottom layers, where the thermoplastic material comprises polyethylene or has a tan delta value of 0.2 to 0.4 within the temperature range of 100° F. to 350° F. The multi-layer substrate can include a cleaning composition loaded onto the multi-layer substrate, where a fluid pathway through the melted thermoplastic material allows the cleaning composition to travel from the top surface layer to the bottom surface layer. The multi-layer substrate may be void of chemical adhesives, where adhesion between the top surface layer and the thermoplastic layer, and between the bottom surface layer and the thermoplastic layer is instead provided by the thermoplastic material itself, which bonds to groups of fibers in the top and bottom surface layers that are in contact with the thermoplastic material as it melts.

Abstract: Pre-moistened wipes that include one or more characteristics correlated to desired properties, such as high durability, mileage, cleaning composition retention, efficacy, or the like are described. Pulp substrates typically include an anionic charge, which can result in binding or retention of a cationic biocide such as a quaternary ammonium compound while the remainder of the composition is released from the wipe (e.g., through squeezing, wiping or other compression). The present wipes are specifically tailored to release at least 20% of the quaternary ammonium compound to a target surface, and exhibit at least a 3-log reduction in Staphylococcus aureus population within about 10 seconds to 5 minutes. Such release and efficacy is achieved without the presence of any cationic biocide release agent (e.g., latex or a cationic salt) included in the cleaning composition or elsewhere within the pre-loaded disinfecting wipe.

Abstract: Methods for manufacturing wipes including melamine entangled into a nonwoven, and associated articles of manufacture. Such a method may include providing a melamine sheet (e.g., contiguous, rather than discrete melamine particles), providing first and second nonwoven sheets, and positioning the melamine sheet between the first and second nonwoven sheets. The sandwich structure is hydro-entangled at high pressure to force the melamine material to become entangled into the nonwoven material, to a degree that a portion of the melamine is actually exposed on the exterior face(s) of the wipe, which are generally provided by the nonwoven sheets. Such a wipe exhibits the drapability of a wipe, with the scrubbing benefits (e.g., very effective cleaning of baseboards, crayon off walls, etc.) of melamine, with greater durability than existing melamine cleaning articles, which tend to quickly crumble during use.

Abstract: A pre-loaded cleaning substrate, and related systems and methods for picking up particles with an aspect ratio (L/D) greater than 300 (e.g., hair), or greater than 1200 (e.g., particularly long hairs). The substrate (e.g., a nonwoven) may include only a single layer of material. The pre-loaded substrate is loaded (e.g., during manufacture) with a cleaning composition. The fibers of the substrate may have an average diameter less than 15 μm, the substrate may have an air permeability of 35 ft3/min to 75 ft3/min, and the liquid cleaning composition may have a surface tension of less than about 50 dynes/cm. Together, the combination of the particular substrate and cleaning composition may facilitate markedly improved ability to pick up high L/D aspect ratio particle debris (e.g., such as hair), while retaining such particles (e.g., providing hair retention index values of at least 20).

Abstract: Pre-moistened wipes that include one or more characteristics correlated to desired properties, such as high durability, mileage, cleaning composition retention, efficacy, or the like are described. Pulp substrates typically include an anionic charge, which can result in binding or retention of a cationic biocide such as a quaternary ammonium compound while the remainder of the composition is released from the wipe (e.g., through squeezing, wiping or other compression). The present wipes are specifically tailored to include a pore size distribution characterized by pores having a size from 300 μm to 400 μm, which is larger than the pore distribution characteristics of existing wipes. Such characteristics increase release of a quaternary ammonium compound to a target surface, providing improved microefficacy, without the need for any cationic biocide release agents such as latex or a cationic salt.

Abstract: Pre-moistened multi-layer wipes in which the fibrous substrate for the wipes comprises 70% or more pulp fibers. The present wipes are specifically tailored to include multiple layers that are adhered to one another with a water-resistant adhesive, e.g., which will maintain good peel strength, even when the multi-layer substrate is loaded with a cleaning composition during manufacture, and stored in such condition for an extended period (e.g., a shelf life of a year or more). The water-resistant adhesive may specifically comprise a ethylene vinyl acetate (e.g., rather than polyvinyl alcohol or other adhesives which do not adequately maintain peel strength), loaded between the layers of the substrate, e.g., up to 10 gsm. The wipe may have a peel strength of at least from 0.15 lbf-in, even after being soaked in the cleaning composition. Such pulp substrate wipes are formed from sustainable materials, while providing desired characteristics of strength and efficacy.

Abstract: Pre-moistened wipes that include one or more characteristics correlated to desired properties, such as high durability, mileage, cleaning composition retention, efficacy, or the like. Pulp substrates typically include an anionic charge, which can result in binding or retention of a cationic biocide such as a quaternary ammonium compound while the remainder of the composition is released from the wipe (e.g., through squeezing, wiping or other compression). The present wipes are specifically tailored to include a mileage absorbency/desorbency factor (“MABDF”) value that is greater than 50. Such characteristics correlate to wipes and substrates that exhibit various desirable properties, such as good handfeel characteristics, improved, more uniform dosing of composition loaded therein, good microefficacy characteristics, and the like.
